- Description:
- This table contains photometric and derived stellar parameters for a sample of 820 solar and late-type stars (the original table of 824 entries had 4 near-duplicate entries for the stars HD 19668, HD 95188, HD 216803 and HD 285382 which have been removed by the HEASARC) from nearby open clusters and the field, including rotation periods and X-ray luminosities. This sample was used by the authors to study the relationship between rotation and stellar activity and derive a new estimate of the convective turnover time. From an unbiased subset of this sample the power law slope of the unsaturated regime, L<sub>X</sub>/L<sub>bol</sub> ~ R<sub>o</sub><sup>beta</sup>, is fit as beta = -2.70 +/- 0.13. This is inconsistent with the canonical beta = -2 slope to a confidence of 5 sigma, and argues for an additional term in the dynamo number equation. From a simple scaling analysis, this implies Delta(Omega)/Omega ~ Omega<sup>0.7</sup>, i.e. the differential rotation of solar-type stars gradually declines as they spin down. Super-saturation is observed for the fastest rotators in this sample and its parametric dependencies are explored. Significant correlations are found with both the corotation radius and the excess polar updraft, the latter theory providing a stronger dependence and being supported by other observations. The authors estimate mass-dependent empirical thresholds for saturation and super- saturation and map out three regimes of coronal emission. Late F-type stars are shown never to pass through the saturated regime, passing straight from super-saturated to unsaturated X-ray emission. The theoretical threshold for coronal stripping is shown to be significantly different from the empirical saturation threshold (R<sub>o</sub> < 0.13), suggesting it is not responsible. Instead, the authors suggest that a different dynamo configuration is at work in stars with saturated coronal emission. This is supported by a correlation between the empirical saturation threshold and the time when stars transition between convective and interface sequences in rotational spin-down models. This table was created by the HEASARC in March 2012 based on <a href="https://cdsarc.cds.unistra.fr/ftp/cats/J/ApJ/743/48">CDS Catalog J/ApJ/743/48</a> file catalog.dat. The original table had 824 entries, including 4 near-duplicate entries for the stars HD 19668, HD 95188, HD 216803 and HD 285382, which have been removed by the HEASARC.

- Sternberg Astronomical Institute Catalog of Supernovae
- Short Name:

- Date:

- Publisher:
- NASA/GSFC HEASARC
- Description:
- This table comprises the Sternberg Astronomical Institute (SAI) Catalog of Supernovae. This version contains data on 2991 extragalactic supernovae (SNe) which were discovered from 1885 until December 12, 2004 and on their host galaxies. Data for host galaxies were compiled from the following catalogues: (1) RC3 (de Vaucouleurs et al. 1991, Cat. <VII/155>); (2) UGC (Nilson 1973. Cat. <VII/26>); (3) PGC (Paturel et al. 1989, Cat. <VII/119>); (4) MCG (Vorontsov-Velyaminov et al. 1962-1968, Cat. <VII/62>, <VII/100>); (5) ESO (Lauberts 1982, Cat. <VII/34>); (6) CfA (Huchra et al. 1994, see Cat <VII/193>), and (7) from van den Bergh (1994, Cat. <J/ApJS/92/219>). The main source of morphological types, major diameters and axial ratios was the RC3; the data from other sources were reduced to the system of RC3. Photographic magnitudes of galaxies were adopted from the UGC and the PGC together with individual data from the literature. The sources of recession velocities or cz values were the RC3, the CfA, the PGC and IAU Circulars. Position angles were taken from the RC3, UGC and the ESO catalogues, and inclination angles were mainly derived from data in RC3 according to Holmberg (1958MeLu2.136....1H). Some data for SNe and host galaxies were adopted from the GCVS (Samus et al. 1995, Cat. <II/205>). This table was created by the HEASARC in June 2005 based on CDS table II/256/sn.dat. Notice that the number of entries (2991) is more than the number of 2780 mentioned in the published reference: this is apparently due to the fact that the CDS table contains supernovae as recent as December 12, 2004, while the latter is complete only until January 6, 2004.

- Stern et al. (2001) BATSE Gamma-Ray Burst Catalog
- Short Name:

- Publisher:
- NASA/GSFC HEASARC
- Description:
- The Stern et al. (2001) BATSE Gamma-Ray Burst (GRB) Catalog was constructed by scanning the archival BATSE daily records (DISCLA data) covering the entire 9.1 years of BATSE's operation. 3906 GRBs were detected, 2068 of which are previously known BATSE triggers while 1838 of them are new non-triggered bursts. All events were detected in the same kind of data with 1.024 seconds time resolution and were processed with the same procedure, and thus constitute a uniform sample. This scan lowers the BATSE detection threshold to ~0.1 photons/s/cm**2. This database table was created at the HEASARC in August 2001 using the file <a href="ftp://ftp.astro.su.se/pub/head/grb/catalogs/etable2.txt">ftp://ftp.astro.su.se/pub/head/grb/catalogs/etable2.txt</a> on the Stockholm Observatory ftp site.

- Subaru Prime Focus Camera (Suprime-Cam) Exposures Log
- Short Name:

- Publisher:
- NASA/GSFC HEASARC
- Description:
- This table contains the Subaru Prime Focus Camera (Suprime-Cam) log of exposures having observation type = 'OBJECT' (those with 'BIAS', 'FLAT' and other types are not included) which have been made since April 2001. Note that from the version of Nov. 2005 on, the number of rows has significantly increased because those data with worse position determination (up to 30 arcsec error) are now included. The data currently extend to November 2005 and it is anticipated that they will be regularly updated Suprime-Cam is an 80-mega pixels (10240 x 8192) mosaic CCD camera, for the wide-field prime focus of the 8.2m Subaru telescope. Suprime-Cam covers a field of view 34' x 27', a unique facility among the 8-10m class telescopes, with a resolution of 0.202 arcseconds per pixel. The focal plane consists of ten high-resistivity 2kx2k CCDs developed by MIT Lincoln Laboratory, which are cooled by a large Stirling-cycle cooler. The CCD readout electronics was designed to be scalable, which allows the multiple read-out of tens of CCDs. It takes 50 seconds to readout entire arrays. A filter-exchange mechanism of the jukebox type is designed that can hold up to ten large filters (205 x 170 x 15 mm<sup>3</sup>). The wide-field corrector is basically a three-lens Wynne-type, but has a new type of atmospheric dispersion corrector. The corrector provides a flat focal plane and an un-vignetted field of view of 30' in diameter. The achieved co-planarity of the focal array mosaic is smaller than 30 um peak-to-peak, which realizes mostly the seeing limited image over the entire field. The median seeing in the I_c-band, measured over one year and a half, is 0.61 arcseconds. The PSF anisotropy in Suprime-Cam images, estimated by stellar ellipticities, is about 2% under this median seeing condition. At the time of its commissioning, Suprime-Cam had the largest survey speed, which is defined as the field of view multiplied by the primary mirror area of the telescope, among those cameras built for sub-arcsecond imaging. For more details, see: Miyazaki et al., Publ. Astron. Soc. Japan 54, 833-853, 2002 (2002PASJ...54..833M).

- Subaru/XMM-Newton Deep Survey X-Ray Source List
- Short Name:
- SXDSCAT
- Date:

- Publisher:
- NASA/GSFC HEASARC
- Description:
- This table contains the X-ray source catalog in the Subaru/XMM-Newton Deep Survey (SXDS). A continuous area of 1.14 deg<sup>2</sup> centered at R.A.= 02h 18m and Dec =- 05 degrees is mapped by seven pointings with XMM-Newton covering the 0.2 - 10 keV band. From the combined images of the EPIC pn and MOS cameras, the authors have detected 866, 1114, 645, and 136 sources with sensitivity limits of 6 x 10<sup>-16</sup>, 8 x 10<sup>-16</sup>, 3 x 10<sup>-15</sup>, and 5 x 10<sup>-15</sup> ergs cm<sup>-2</sup> s<sup>-1</sup> in the 0.5 - 2, 0.5 - 4.5, 2 - 10, and 4.5 - 10 keV bands, respectively, with detection likelihood >=7 (corresponding to a confidence level of 99.91%). The catalog consists of 1245 sources in total, including 32 extended-source candidates. The averaged log N-log S relations are in good agreement with previous results, bridging the flux range between Chandra deep surveys and brighter surveys. The log N-log S relations show significant spatial variation among pointings on a scale of 0.2 deg<sup>2</sup>. Analyzing the autocorrelation function, the authors detect significant clustering signals from the 0.5 - 2 keV band sample, which can be fit with a power-law form (theta/theta<sub>c</sub>)<sup>(-0.8)</sup> with a correlation length of theta<sub>c</sub> of 5.9 (+1.0, -0.9) arcsec when the integral constraint term is included. In the 2 - 10 keV band, however, the clustering is not significant, with a 90% upper limit of theta<sub>c</sub> < 1.5 arcsec. This table was created by the HEASARC in November 2008 based on an electronic version of Table 2 of the reference paper obtained from the Astrophysical Journal website.

- Sunyaev-Zeldovich Array 31-GHZ Radio Source Catalog
- Short Name:
- SZA31GHZ
- Date:
- 07 Mar 2025
- Publisher:
- NASA/GSFC HEASARC
- Description:
- This table contains the first sample of 31-GHz selected sources to flux levels of 1 mJy. From late-2005 to mid-2007, the Sunyaev-Zel'dovich Array (SZA) observed 7.7 deg<sup>2</sup> of the sky at 31 GHz to a median rms of 0.18 mJy/beam. The authors identify 209 sources at greater than 5-sigma significance in the 31-GHz maps, ranging in flux from 0.7 mJy to ~200 mJy. Archival NRAO VLA Sky Survey (NVSS) data at 1.4 GHz and observations at 5 GHz with the Very Large Array are used to characterize the sources. The authors determine the maximum-likelihood integrated source count to be N(>S) = (27.2 +/- 2.5) deg<sup>-2</sup> * (S<sub>mJy</sub>)<sup>(-1.18 +/- 0.12)</sup> over the flux range 0.7 - 15 mJy. This result is significantly higher than predictions based on 1.4-GHz selected samples, a discrepancy which can be explained by a small shift in the spectral index distribution for faint 1.4-GHz sources. From comparison with previous measurements of sources within the central arcminute of massive clusters, the authors derive an overdensity of 6.8 +/- 4.4 deg<sup>-2</sup>, relative to field sources. The SZA is an interferometer designed specifically for detecting and imaging the Sunyaev-Zel'dovich (SZ) effect in galaxy clusters, and is located at the Owens Valley Radio Observatory (OVRO). The SZA is equipped with an 8-GHz wideband correlator and sensitive 26GHZ-36GHz receivers. The data in the SZA survey correspond to 1493 tracks taken between 2005 November 13 and 2007 July 25. The data in the CMB anisotropy measurements correspond to an additional 414 tracks taken between 2005 November 12 and 2007 October 25. The analysis in this paper refers to the full 1907 tracks taken in both observing modes. To complement the NVSS and FIRST observations, the authors obtained high-sensitivity VLA observations at 5 GHz between 2007 February 24 and 2007 April 15. This table was created by the HEASARC in June 2102 based on <a href="https://cdsarc.cds.unistra.fr/ftp/cats/J/ApJ/716/521">CDS Catalog J/ApJ/716/521</a> file table3.dat. Some of the values for the name parameter in the HEASARC's implementation of this table were corrected in April 2018. This is a service provided by NASA HEASARC .

- Publisher:
- NASA/GSFC HEASARC
- Description:
- This database table contains information of the events detected by the Wide-band All-sky Monitor (WAM) on Suzaku during its ~10 years of operation. Each event has associated data products. The lightcurves are derived from the on-board operating modes that collected the WAM data from each of the sub-detectors. The lightcurves are rates as a function of time in different energy bands, and they can be used with the general FITS tools within HEAsoft or XRONOS. Version 3 of the lightcurves were generated at HEASARC from the version 2 files, and they are now the final versions hosted at both HEASARC and DARTS. This database table reflects version 3 of the data products. <p> Version 2 of the FITS lightcurves and their plots were generated at Saitama University in Japan and a copy hosted at the DARTS archive, located at ISAS (<a href="http://www.darts.isas.ac.jp/pub/suzaku/wam-2.0/">http://www.darts.isas.ac.jp/pub/suzaku/wam-2.0/</a>).

- Publisher:
- NASA/GSFC HEASARC
- Description:
- The Suzaku XIS detector units can be configured differently depending on how the user chooses the observation to be carried out. This database table records for each Suzaku observation the different XIS configurations during an observation for all XIS units. The set of parameters that can be configured are: datamode (see also edit mode), window size, on-board window discriminator, on-board grading and event threshold. Each record lists for a given XIS the values set for these parameters in the time interval where they are valid within the observation. Therefore for a given XIS there will be as many records as many different configurations are present within an observation. This database table is generated at the Suzaku processing site. During operation, it is updated on daily basis. This is a service provided by NASA HEASARC .

- SwiftAGN&ClusterSurvey(SACS)Hard-Band(2-10keV)PointSourceCatalog
- Short Name:
- SACSHPSCAT
- Date:

- Publisher:
- NASA/GSFC HEASARC
- Description:
- The Swift Active galactic nucleus (AGN) and Cluster Survey (SACS) uses 125 deg<sup>2</sup> of Swift X-ray Telescope (XRT) serendipitous fields with variable depths surrounding gamma-ray bursts to provide a medium depth (4 x 10<sup>-15</sup> erg cm<sup>-2</sup> s<sup>-1</sup>) and medium area survey filling the gap between deep, narrow Chandra/XMM-Newton surveys and wide, shallow ROSAT surveys. In the reference paper, a catalog of 22,563 point sources and 442 extended sources, and the number counts of the AGN and galaxy cluster populations are presented. SACS provides excellent constraints on the AGN number counts at the bright end with negligible uncertainties due to cosmic variance, and these constraints are consistent with previous measurements. The authors use Wide-field Infrared Survey Explorer (WISE) mid-infrared(MIR) colors to classify the sources. For AGNs, they can roughly separate the point sources into MIR-red and MIR-blue AGNs, finding roughly equal numbers of each type in the soft X-ray band (0.5-2.0 keV), but fewer MIR-blue sources in the hard X-ray band (2-8 keV). The cluster number counts, with 5% uncertainties from cosmic variance, are also consistent with previous surveys but span a much larger continuous flux range. Deep optical or IR followup observations of this cluster sample will significantly increase the number of higher redshift (z > 0.5) X-ray-selected clusters. This HEASARC table contains the list of 10,060 Swift XRT point sources which were detected in the hard X-ray band image (2-10 keV) using wavdetect with a false positive threshold of 10<sup>-6</sup> (contained in Table 3 of the reference paper). The authors consider these sources to be AGN candidates. This table was created by the HEASARC in June 2015 based on an electronic version of Table 3 of the reference paper, the list of Swift XRT point sources detected in the hard X-ray (2-10 keV) band, which was obtained from the ApJS web site.
